Invention relates to the use of the possibility of the function (function of device-to-device) by the direct link between mobile communication equipment.
Background technology
Common Information Mobile Service (that is, the service provided by mobile telephone network, for example, audio call, video call, SMS,
MMS) may relate to it is being associated from different mobile telecom network operators, belong to different public land mobile networks (" PLMN ")
Subscriber mobile communication equipment (for brevity, hereinafter also referred to " mobile equipment ").
In order to establish service (that is, to enable providing service to the subscriber of different PLMN) between PLMN, it usually needs
The interconnection path for being used for both signaling and communication is established between involved PLMN.
Intercommunication (interworking) between the PLMN of different operators is usually by positioned at the logic side of each PLMN
Dedicated gateway at boundary is established.Established between different PLMN interconnection path be typically based on limited quantity parameter it is mutual
Exchange, for example, the address of borde gateway, subscriber information register (for example, attaching position register in 2G/3G networks-
HLR, it comprising be authorized to be registered to some PLMN, the PLMN each mobile device subscribers details central data
Storehouse) etc., to make to minimize for the configuration effort made and the data volume to be swapped between PLMN.These parameters are usual
Configured in a manner of semipermanent, to make to change the temporal of needs for involved PLMN additional configurations and test
Become and minimize.
3GPP (" third generation partner programs (3rdGeneration Partnership Project) " initial
Abbreviation) the 12nd edition standard external member of LTE (Long Term Evolution) advanced (LTE-A) had been incorporated into and supported based on close service (also referred to as
For " ProSe ") required technical functionality, should based on close service based between the mobile equipment in licensed spectrum (D2D,
Device-to-device) direct link.The direct discovery that such function is allowed between mobile equipment (means to move
Equipment can be found that the close mobile equipment for broadcasting short-text message (being typically advertisement information)) and communicate (close
The foundation of direct communication between mobile equipment).Close mobile equipment is intended that to be differed just at from several meters to hundreds of meters

Embodiment
Fig. 1 depicts the scene of ProSe service provisions between mobile network.
Reference numeral 105 and 110 represents two different mobile networks, for example, for example belonging to two different telecommunications networks
Two different PLMN of network operator.PLMN 105 and 110 is such as the 4th generation (" 4G ") cellular network, such as 3GPP LTE-
A cellular networks.
As it is known, 3GPP LTE-A cellular networks (such as PLMN 105 and 110) include radio access network (E-
) and core network (evolution block core or EPC) UTRAN.E-UTRAN include multiple transceiver nodes or station, also referred to as
ENodeB (" enode b ").ENodeB provides the network cell for being divided into configurable number (for example, typical configuration is
Three cells) geographic area on radio covering, for into each network cell mobile equipment (subscriber's installation or
UE, such as smart phone, tablet computer, tablet phone) service is provided (for example, web-browsing, Email, voice communication, regarding
Frequency call, audio and/or video streaming).
In fig. 1 it is shown that three UE：It is attached to two UE 125 and 126 of PLMN A 105 and is attached to PLMN
Another UE 130 of B 110.
Hereinafter, the PLMN between PLMN involved in ProSe services is referred to as the " PLMN " of ProSe interconnection.With reference to figure 1,
PLMN 105 and 110 is intended that the PLMN of ProSe interconnection.The example that ProSe is serviced between PLMN is direct discovery service, it causes
Different but geographically close UE (having suitable ability) can directly find each other, even if different UE (such as UE
125 and UE 130) be different PLMN (such as PLMN 105 and 110) subscriber.
Moreover, hereinafter, " PLMN " of subscriber refers to the PLMN being connected to appended by UE, i.e. serves " the clothes of this UE
Be engaged in PLMN ".The PLMN of subscriber for example can be Home PLMN, i.e. the owner of UE its subscription of warp-wise is used for delivery service (bag
ProSe between such as PLMN is included to service) commercial license PLMN.For example, when the covering of angelica PLMN is unavailable, belonging to
In the case of (domestic or international) Roaming agreements between PLMN and the PLMN different from Home PLMN (that is, " visited PLMN "),
UE is it may happen that be attached to visited PLMN.With reference to figure 1, PLMN 105 is the PLMN for the subscriber of UE 125 and 126 (because false
Determine UE 125 and 126 and be attached to PLMN A 105), and PLMN 130 be for the subscriber of UE 130 PLMN (as it is assumed that
UE 130 is attached to PLMN B 110).It means that the subscriber profiles associated with the UE owners that its UE is attached to PLMN by
The HSS (for example, HSS 120 for the HSS 115 of PLMN A 105 and for PLMN B 110) of Home PLMN is so that ordering
It can be used in the PLMN at family.
It is described below and is related to exemplary ProSe services, this is direct discovery service, but described concept can also
It is applied to directly exchange any other ProSe services of data among the mobile equipment across different PLMN.
With reference to figure 2, five key steps are included according to the method for the embodiment of solution disclosed herein.
In first step (step 1, square frame 205) or " UE selections " step, selection and configuration are attached to its subscriber's
A UE of PLMN or two or more UE, to obtain the relevant configuration datas of ProSe, is included in the PLMN of ProSe interconnection
The PLMN radio resources of the ProSe interconnection of middle distribution.As an example, with reference to figure 1, the PLMN for being attached to its subscriber have selected
105 UE 125 is to obtain the relevant configuration datas of the ProSe of PLMN B 110.By such as PLMN A 105 select and configure with
It is ownership that the one, two or more UE for obtaining the relevant configuration datas of ProSe, which can be PLMN A 105 relative to it,
The UE of PLMN, or PLMN A 105 are that the UE of visited PLMN (that is, is attached to PLMN A 105 in roaming for it
UE)。
In second step (step 2, square frame 210) or " resource distribution acquisition " step, the UE of (one or more) selection
Obtained according to any effective solution, such as current 3GPP solutions (for example, as illustrated in TS 36.331)
The relevant configuration datas of ProSe are taken (to be included in the PLMN radio money of the ProSe interconnection distributed in the PLMN of ProSe interconnection
Source).
In third step (step 3, square frame 215) or " resource distribution report " step, the UE of (one or more) selection
The acquired relevant configuration datas of ProSe are reported to the PLMN to its subscriber.As explanation, with reference to figure 1, it is assumed that PLMN A
105 have been selected and are configured with UE 125 to obtain the relevant configuration datas of ProSe, then PLMN As of the UE 125 to its subscriber
105 reports are acquired, the relevant configuration datas of ProSe of the PLMN B 110 of ProSe interconnection.
In four steps (step 4, square frame 220) or " resource distribution validity check and broadcast " step, subscriber's
PLMN for example indicates the relevant configuration numbers of ProSe using signaling broadcast channel (for example, SIB 19) to its other UE are attached to
According to make them can be used for the UE with ProSe abilities interested of this PLMN, for example, the UE of PLMN A 105
125 and 126.Alternately, possible different mechanisms are that the PLMN of subscriber is for example relevant by ProSe via dedicated RRC signaling
Configuration data is only sent to be attached to its UE with ProSe abilities, so that using the ProSe abilities of UE (as in PLMN
Specified by HSS).Alternatively or additionally, as being relatively described in detail below, it is attached to PLMN and such
The UE that PLMN selects and be configured to obtain the relevant configuration datas of ProSe can feel emerging by D2D channels to ProSe services
Other close UE of interest directly provide relevant information (under identical or different PLMN).
In the 5th step (step 5, square frame 225) or " for the triggering of resource distribution renewal " step, subscriber's
The UE that PLMN or be chosen so as to obtains the relevant configuration datas of ProSe recognizes at present to need its available information the feelings that update
Under condition, which restarts from step 1.
Hereinafter, step listed above is described in greater detail.
Step 1 (square frame 205), " UE selections "
In this step, the choosing to being assigned (one or more) UE for obtaining the relevant configuration datas of ProSe is performed
Select, the relevant configuration datas of ProSe are included in the radio resource of ProSe distribution in the PLMN of ProSe interconnection.
UE selections can be carried out according to two kinds of replacement mechanisms：First mechanism is the UE selection machines of network (PLMN) control
System, and the second mechanism is autonomous UE selection mechanisms.
The UE selections of network control
According to this method, service PLMN selects one or more of its UE serviced for obtaining according to following principle
Take the relevant configuration datas of ProSe of the PLMN of ProSe interconnection：
The standard of 1.UE selections
Due to obtaining general ability (that is, SIB reading capability) of the relevant configuration datas of ProSE based on UE by UE,
Any UE is to be adapted to selected candidate in principle.This gives network huge selection flexibility.For selecting (one or more
It is a) a possible standard of UE is random selection.In addition to randomly choosing the basic possibilities of UE, it can also apply following
Standard：
a.Selection has subscribed to the UE that ProSe is serviced and had ProSe abilities so that only ProSe is serviced actual
Upper those UE interested can be selected to perform the acquisition task of the relevant configuration datas of ProSE.Subscribe to data and UE energy
The knowledge of force data is typically based on own subscription profile and UE abilities can be used for servicing PLMN：The profile of general UE is registered in PLMN's
In HSS, and service PLMN and know UE abilities in each connection establishment stage.
b.The selection of UE can further be refined by considering the following：
- traffic profile (for example, selection is used for the UE of the usually machine to machine service with definite transmission activity)；
- it is past search (for example, not selecting to have made the UE of search)；
- higher than the radio link quality of radio link quality threshold；
- UE positions (for example, selecting the UE of the geographically cell of closer other PLMN)；
- UE loads (for example, not selecting the UE with ongoing data session).
The quantity for the UE to be selected in network cell is substantially less than the total number of mobile communication equipment in network cell.
The quantity for the UE to be selected can change, the UE such as (but not limited to) from one to five from one to several units.It is selected
The quantity of the UE selected may rely on the type of the service involved by flow load, the size of network cell and UE.In process
Involved in UE quantity it is more, the successful probability of the process it is higher and complete it spend time it is shorter.On the contrary, for
The processing load of eNodeB increases with the increase of the quantity of selected UE, with all data received of cross-check.
The frequency of 2.UE selections
The selection for being assigned (one or more) UE for obtaining the relevant configuration datas of ProSe is performed by servicing PLMN, with
Just obtain and update the relevant configuration datas of ProSe (when they change).It can be suitable for keeping the time of information updating
Cycle (for example, daily or different cycles based on experience) periodically carries out selection, or can be with the side based on event
Formula performs selection, i.e. is performed when some no longer valid event of the relevant configuration datas of ProSe that instruction had previously obtained occurs
Selection (this explains the step 5 below with reference to this method in more detail).
3. the process for UE selections
Following alternative is possible.
A. connection mode UE
In this case, servicing PLMN (for example, eNodeB of service PLMN) there is UE to select required letter
Cease (UE profiles and ability) and can select to be assigned (one or more) UE for obtaining the relevant configuration datas of ProSe.
B. idle pulley UE
In order to manage this scene, it is necessary to relative to the mechanism contemplated in Current standards some new mechanism：
I. service PLMN sends new special " paging message " using common broadcast paging channel in its controlled cell.This
Kind paging message should include " ProSe services " field as specific information, related to obtaining ProSe its object is to address
Configuration data any UE interested；
Ii. in order to carry out response to such paging message, UE interested should be established with new special " reason
New RRC (radio resource control) connections of value " (this why be UE just being indicated generally in answer page) and enter
Into connection mode.Afterwards, the process is identical with the situation (the entry a. of the above) of connection mode.
This new mechanism is described in figure 3.When PLMN (for example, PLMN A 105) needs to select to be used to obtain ProSe phases
During the UE of the configuration data of pass (square frame 300), the broadcast of new special paging message 305 (by eNodeB of that PLMN)；Paging
Message 305 can include such instruction：The paging message is given birth to for the purpose of ProSe UE selections and configuration between PLMN
Into paging message, to collect the candidate UE for being suitable for successful search.Candidate UE (UEx in Fig. 3, such as the UE in Fig. 1
125) paged by establishing new RRC (radio resource control) connections with new special " cause value " come response (310)
Message, to inform：They are establishing such connection so as to special (ad hoc) the ProSe paging messages of response.In addition,
UE can provide information to help and select the successful UE of most probable, particularly the measurement of requested cell.By this way, first
The preceding UE in idle pulley becomes connection mode UE, and for the side of connection mode UE selections under previously described entry a.
Method is applicable in (315).
UE is independently selected
In this case, different from the UE selections of network control, one or more UE perform self selective to obtain
The relevant configuration datas of ProSe, without any clear request of the service eNodeB of the PLMN of themselves.Due to this
The method either mode based on event still all controls from network on a periodic basis, therefore its result may be by
It is limited or infrequently and relatively inaccurate in the report of the UE of self selective.Therefore, this method should preferably require to be related to
The UE (higher than in the case of the UE selections that network controls) of relative high number, to make asynchronous acquisitions and report of the UE to information
It is relatively accurate and frequent.
Selected as the UE of network control, the standard for UE self selectives can be based on but be not limited to as being stored in PLMN
HSS in UE abilities and user service profile, wherein UE abilities can include the instruction of D2D abilities, and user service letter
Shelves can include on the subscription serviced ProSe and the information of mandate.
Autonomous, self selective associated trigger for UE can be：The relevant configuration datas of currently available ProSe are not
It is effective again.This means to monitoring that the UE interested of the ProSe resources on other PLMN does not have in indicated radio resource
Find and service relevant any content with ProSe, i.e. UE cannot decode the content in the resource.
Step 2 (square frame 210), resource distribution obtain
In this step, the relevant configuration datas of ProSe (radio resource information) of the PLMN of ProSe interconnection are by institute
The UE (selecting in step 1) of selection is obtained based on any conventional mechanism, such as, for example, the mechanism of 3GPP the 12nd edition, such as exists
Illustrated in TS 36.331.More specifically, according to TS 36.331, the Radio Service Node serviced in PLMN can lead to
Cross its broadcast signaling channel (for example, in SIB 19 or other correlations SIB) provide UE it can be performed search, frequency with
And the list of relevant PLMN identifiers (ID), so as to find thereon indicate the relevant radio configuration data of ProSe those
The signaling broadcast channel of PLMN.
Step 3 (square frame 215), resource distribution report
Once selected UE has obtained the relevant configuration data (radio resources of ProSe of the PLMN of ProSe interconnection
Information), acquired data report just should be serviced PLMN and/or other UE by UE to it.This can be according to different methods
To perform：
1. to service PLMN reports：
A. reported by RRC signaling
Configuration message can be sent via RRC signaling to UE by servicing PLMN (that is, the eNodeB for servicing PLMN), to ask
UE performs specific measurement.Configure message and include the requested required full detail of measurement of UE execution.Configuring message can be with
Based on the current 3GPP signaling messages of the relevant Information expansions of above-mentioned ProSe (for example, " measuring configuration ", " measurement of record is matched somebody with somebody
Put " or " UE information requests ") in one, or new RRC information designed for this purpose.According to the configuration received, UE can
To provide requested measurement immediately after source configuration data is obtained, or requested measurement is supplied to subsequently by delay
Stage, for example, when RRC connections due to UE is in idle pulley and it is unavailable when.
B. exclusive data connection is established
In this case, be selected for obtain the relevant configuration datas of ProSe UE establish exclusive data connection with
The acquired relevant configuration datas of ProSe are reported to the particular server serviced to it in PLMN.As shown in Figure 4 schematically
, the RRC signaling of eNodeB is not to rely on, but the ProSe functions 405 of servicing PLMN (that is, manage and are used for ProSe services
UE PLMN controllers entity) provide to UE that ProSe is relevant to be matched somebody with somebody for example according to the mechanism defined in 3GPP TS 23.303
Put parameter.According to such mechanism, ProSe functions 405 connect to the UE involved in ProSe services via IP and send (410) fortune
Whole configuration parameters of row ProSe services.Such configuration parameter includes being exclusively used in the server for collecting the report from UE
The logical address of (ProSe configuration datas server) 415.The logical address of server 415 configures in UE.Then UE can be reported
Accuse the relevant configuration datas of ProSe acquired in (420).Address configuration can be with all other relevant configuration parameters of ProSe
It is sent collectively to UE.The situation that this method is selected particularly suitable for autonomous UE.
Once service the relevant configuration datas of ProSe (the radio money that PLMN has received the PLMN of ProSe interconnection via UE
Source information), service PLMN should just check the validity of the data received.
In embodiment, in order to establish the reliability of the data received, define and report the information after renewal to clothes
The threshold value of the quantitative aspects of the mobile equipment of business PLMN.Specifically, only in a certain number of UE (for example, 3 or 5
Or more) independently report identical configuration data after, the data received will just be considered having updated.
2. directly spread by the UE of ProSe abilities
Will be acquired to service PLMN or replacement except reporting the acquired relevant configuration datas of ProSe
The relevant configuration datas of ProSe, which are reported, gives service PLMN, and UE can also use ProSe abilities, and acquired ProSe is relevant
Configuration data is transmitted directly to other equipment interested, i.e. UE is using its D2D ability come will be acquired by D2D channels
The relevant configuration datas of ProSe are transmitted to services other close UE interested (in identical or different PLMN to ProSe
In).In this case, according to existing D2D processes, it can use and be shared by the way that ProSe codes are exclusively used in configuration data
Method.
In fact, the solution directly found for ProSe defined by 3GPP in TS 23.303 (as illustrated
) hypothesis UE should notice its presence by the radio resource as broadcast channel.Short text information can be believed with existing
Breath provides together in itself, to enable the service of such as advertisement etc.All these information are according to defined in TS 23.303
Rule is encoded.Especially, code tree is defined, wherein each branch is exclusively used in a kind of service.According to embodiment, code
Branch is used to notice the relevant configuration datas of ProSe.This method have preserve from UE to service PLMN and from service PLMN
To other UE involved in ProSe signaling report the advantages of.
Step 4 (square frame 220), resource distribution broadcast
In the feelings not spread directly using UE is carried out to the acquired relevant configuration datas of ProSe by ProSe abilities
Under condition (or in addition additionally), reported by its selected service UE to the PLMN's of the ProSe interconnection of service PLMN
The relevant configuration datas of ProSe (radio resource information) (that is, can be made by servicing PLMN by using existing 3GPP frames
With system information broadcast or dedicated RRC signaling D2D is controlled to operate) send, wherein Current standards information passes through by selected
UE collect and the relevant configuration datas of ProSe (radio resource information) of PLMN of the ProSe of report interconnection are enriched.
This may need to extend current SIB or new special SIB.The additional information of the relevant configuration datas of ProSe can include but
It is not limited to：
·PLMN ID；
Cell ID；
Carrier frequency；
Frequency sub-information (for example, Physical Resource Block-PRB in LTE), it is to be in the PLMN of ProSe interconnection
The detailed resource pond of ProSe monitoring distribution；
(it is how close that validity timer can represent that provided information has to validity timer.This contribute to triggering/no
Trigger information updating).
No matter employed in previous steps which kind of reporting option (for example, 1.a.-" being reported by RRC signaling "-and
1.b.-" establishing exclusive data connection "), this mechanism can be used.
If employ " being reported by RRC signaling ", then the configuration data for being obtained by UE and being collected by eNodeB
Handled by the management function (for example, autonomous/self-organizing network-SON-function) in network, it is by matching somebody with somebody in eNodeB
Management process is put to configure the resource distribution after the renewal of UE to be broadcast to.
If employ " establishing exclusive data connection ", then received by ProSe configuration datas server (415 in Fig. 4)
The information collected can be handled by the management function (for example, autonomous/SON functions) in network, it is by eNodeB
Configuration management process configures the resource distribution after the renewal of UE to be broadcast to.
Step 5 (square frame 225), for the triggering of resource distribution renewal
It is corresponding in the PLMN of other ProSe interconnection when PLMN changes the relevant radio configuration data of its ProSe
Information result it is out-of-date (ourdate).In this case, indicated radio will not be in by other PLMN UE serviced
The relevant radio configuration data of the ProSe associated with that PLMN are found in resource；In practice, serviced by other PLMN
UE will cannot decode information on those resources.
In order to cause the information associated with the relevant radio configuration data of ProSe to protect in the PLMN that ProSe is interconnected
Renewal is held, it is possible to have several mechanism, such as：
·What network was initiated periodically updates：PLMN is periodically updated process, and (cycle of renewal shall be appropriate for
Minimize out of service time)；
·The renewal that UE is initiated：When (side) available information is out-of-date in terms of UE is recognized at it, it pass through to
Service PLMN sends warning to notify service PLMN.Based on this warning, network is updated process.Such as reported in resource distribution
In (above-mentioned steps 3) like that, the renewal process that UE is initiated requires UE to establish exclusive data connection, and exclusive data connection has example
Such as collect UE report identical ProSe configuration datas server 415 as target (referring to step 3,1.b. establish exclusive data company
Connect).
The UE of network assistance is from home court scape：It is based on the validity timing associated with the relevant configuration datas of ProSe
Device；Once validity timer expires, UE can run the autonomous acquisition of the relevant configuration datas of ProSe after renewal.
